To all whom t may concern; Y Y

Be it known that I, ERNEST W. JONES, a citizen of the United States,cand resident of San Jose, county of SantaClara, and State of California, have invented anew and useful BabbittingDevice, of which the following` is a specification. c v he present invention relates to improvements in babbitting, boring and scraping l0 machines adaptedto be usedin re-babbittirig Worn outbearings of auto'mobilecoliiiiectiig rods or the like. I ts Vprincipal object to provide a simplemachinecf the character @scribed of convenient size, such as can' be easily handled by theiowner of a small automoblle repair Shop, which will enable the latter to reba'bbitt the bearing in a short time and to get the bore Yshaped and `lis'lfed to answer all the requirementsv of t e bearing. The device I wish to secure Letters Patent on is now in Successful operation and enables me to re-babbitt a bearing in about or 40 minutes and to get it in such shape that I hardly ever have to do any adjusting after the machine has performed its work.

The principles involved in my invention are embodied in the mechanism illustrated in the accompanying drawing, WhichFigure 1 represents a side viewnoi my device, 30 Figure 2 a sectional view along line 2--2`0 Figure 1, Figure 3 a perspectivel View' of. a planing tool used in connection with myrdevice, Figure 4 an enlarged. sectional view through the principal working parts of my device along line 4 4 of Figure 2 Figure 5 a detail view of ascraping and' tool, shown in its positionui a used in my device, Figure 6 a cross-section through said tool and shaft along line lof Figure 5, Figure 7 an enlarged detail View showing the manner of securing) the planing tool shown in Figure 3 in the `shaft mentioned before, Figure 8 a detail View of a borin tool used in connection with my devicenan ure 9 a detail view of a spring collar used 1h connection with my device'. k Referring to the `dra'v'v'ing's in detail', show my babbitting device as, bains subported between two strong horizonte; ,izeel plates 1) and (2'): placdwecifalh.. abi-ire each other and` firmly secured to a post' by means of bolts (4) peetratrng'psrt and vertical members (62Al which are`,i`rrteg'ral parts, of' the horiz/onta] p my deyihe.

.of which will be described hereafter.

used in connection with the finishingof the bearing. l show three of these tools in my drawing, the planing and bevelling tool (31), the boring tool (32) and the boring and shaving' tool (33), the particular ulsges Q tween the lower plate and the bearing l provide a large Washer (34) having an internal thread. I also use in the babbitting operation two spring collars (36), one of which is shown in detail in Figure 9. It consists of an inner spring (37) and an outer spring (38). The inner spring is somewhat longer y than the outer one and adapted to be pressed into circular form by the latterwhich, when expanded, does not quite complete a circle, but ma be made to approachand complete the ful circle by pressing together the two anges (39). The latter two are secured to each other at any desired distance by a spiral spring (41), which is fastened to one of the flanges and may be slipped `over the other one so as to hold the same at the desired distance.

To, brace the studs (12) `I use two rods (42) one end of which is secured in the vertical member (6) or the angle irons secured thereto, while the otherV end is secured in the angle iron (20) supporting the connecting rod, so that the whole forms a firm structure offering no chance whatever for any vibration of the connecting rod or the bearing container while .thebearing is being formed. A spring (43)v slidable on the shaft (7), a plurality of auxiliary tubes (44) secured near the top of the shaft s o as to be out of theway when not usedand a handle (46) for turning Vthe .rod complete the apparatus, which is operated as follows:

Insert the connecting rod between the two plates of the first pair of rods (12) and -between the angle and the plate of the second pair of rods so that the one half of the bearing container forming part of the connecting rod is approximately in its right pllace around the shaft (7 Place the other alf against it so as to enclose the shaft completely, the sheets of cardboard having been interposed. Insert the rods (21) through the bolt holes of thebearing container, securing them at the outer end by the pin l(2,3), which is chained to the bracing rod (42) and adjust the bearing container so as to make it concentric with the shaft. ln this operation the bevalling tool (31) maybe used, which may be inserted, bevelled edge down` in the slot (28) adjusted in the same by means of the sca e on the same and then lowered into the bearing container by turning the shaft (7), when its bevelled edge will make contact with the dge of the bearing container and center the atter.

After the bearing c ntainer hasA beenv properly centered, itis rmly secured in its Vproper place by tightening the various nuts holding the same. One of the spring collars (36) is placed on top of the bearing, tightened to a desired degree so as to allow a Bange to be molded on top of the bearing, and secured there by means of two spiral springs (48) fastened to the bracing rods (42). The other spring collar (36) is secured in a similar manner to the bottom of the bearing and supported by the washer (34), after which a coat of plaster of Paris is applied to seal any small holes or cracks which-might allow the babbitt to run Aout. The shaft is heated to allow the babbitt to flow freely and the molten babbitt is then poured into the form, the spring collars allowing the babbitt to flow beyond the bearing proper and to form a flange at either end of the bearing. The babbitt is then allowed to cool for ten or fifteen minutes, whereupon the spring collars are removed, the washer let down on the shaft and the latter, which is slightly tapered, as shown in Figure 4, withdrawn upwardly vby turning it to the right, the thread being lefthanded.

Assuming a bearing of 1-1/4 inch diameter is desired and the shaft has a diameter of 1/64 inch less than that, the next step to be taken is to insert the boring and shaving tool into the slot (28). The latter tool is shown in cross-section in Figure 6, is of suiicient length to cover the whole bearing at one time so as to cut off a thin yslice of the same, and is secured in the slot by means of set screws (40) inserted into countersunk holes so as not to interfere with the operation. At the lower end of the tool I provide a number of steps (51) which allow the same to be used as a bearing tool. As will be seen from the drawing. thc cutting edge of the tool drags behind the force actuating it, whereby a smooth surface is secured and all chattering prevented. After this tool has been inserted in the slot, it is lowered into the bearing, set to cut ofi' any desired amount and secured by the set screws. VThe shaft is then rotated and in this vmanner a smooth surface secured.

The scraping tool is then removed from -the slot and the planing tool (31) inserted.

.then removed, the shaft lowered so as to bring the slot below the bearing, the plane inserted again upside down, the spring placed below it and supported by the washer (3,4), whereupon the shaft is turned to the l IID right and the lower flange of the babbitt planed. To bevel the inner edge of thel babbitt the same tool is used in the same manner with the only exception that the same is inverted during each operation, so that the bevelling edge comes in contact with the babbitt.

The bearing is now ready to be used and I have found in actual experience that in practically all the cases it makes a perfect fit and does not require any further handling or adjusting.

Assuming now that the bearing has to be larger than 1-1/4 inches in diameter, say 1-1/`2 inches: In that case I first use my boring tools (32) after the spring collars have been removed. As shown in the drawing in Figure (8), this tool consists of a threaded rod adapted to be screwed into the Shaft transversely of its axis and having one or two cutting edges adapted to cut a corresponding strip of metal out of the bearing as the shaft is screwed upward or downward. The threads are arranged to run 32 to the inch so that one full turn of the boring tool will cause the same to enlarge its circle a 1/16 part of an inch. One of these boring tools is screwed into the 4threaded hole (52) below the bearing, which I preferably use for cutting a thin slice out of the bearing so as to provide clearance between the shaft and the bearing, without putting an undue strain on the shaft. Another one of these boring tools is permanently secured in the shaft above the bearing, that is, just below the slot (28), and this tool is used to do the real work of increasing the diameter of the hole. It may cut as much as 1/4 inch of metal at a time, that is, increase the diameter by 1/2 inch, without overstraining the shaft, because there is no danger of the shaft springing. since it is pulled downward. After the size of thehole has been increased to the desired dimension, the scraping tool (33) and the planing tool (31) are used in the same manner as beore.

In order to reduce the amount of boring necessary to obtain the desired size of hole, I provide the tubes (44) on the shaft (7), which are normally telescoped over each other and supported by a hinged plate (54) near the top of the shaft. The plate itself is held by a spring (56) which is adapted to yield to pressure so that the sleeves may be caused to pass it and to slide down the shaft so as to increase the diameter of the same at the place where the babbtting is to be done, so that the original hole in the bearing may be made of a size coming somewhat nearer the desired diameter.
